The collars 23 end 24 are provided with blades 30 and 31, respectively, disposed at reverse inclinations to each other as shown particularly in Figs. 2, 3 and 4, the said rollz'n's being preferably disposed upon the sho'lts 10 and l] in such relative positions that its the shafts rotate in the directions in dicated by the arrows in Figs. 1 and 2, cor responding blades upon the shafts are disposed opposite each other and the blades on each shalt ere spirally arranged. in this inunner the shafts need be spaced apart only at such distances that the blades of oni-ushztlt will clear the collar portion upon the other shaft, the blades themselves never coming As shown in.

W lat I claim is:-

A mixing apparatus comprising a casing with a plurality of concave bottoms therein which are divided by an upwardly extended longitudinal rib, a rotatable shaft for eaeh l m presenee of two witnesses.

of the bottoms having eollars thereon provided with blades which are eonstrueted ((illCflVG-(ODVOX their entire lengths, and arranged spirally at an angle to their respective shafts, said shafts being s need at suitable distanee apart and the bades on one shaft extending to near the collars on the opposite shaft and mining substantially n )5 continuous floor, so as to be adapted to throw the material in. eontinous masses over the ridge into tho mljoining eoneztve bottom, substantially as speei'lied.

in testimony whereof I :LlllX my signature 2o Witnesses:
